- Abstract
Thermoacoustic engine technology has been applied to convert heat energy into acoustic energy for the purpose of electricity generation. However, linear alternators are relatively expensive. Recently, SCORE (www.score.uk.com) has successfully developed 22.7 watts of electricity power using a Thermo-Acoustic engine (TAE) with an ordinary audio loudspeaker as a linear alternator. However, the power-transduction efficiency of loudspeakers is usually poor due to their physical properties such as paper cones are weak and fragile, strokes are limited, and their impedances are poorly matched to gas at high pressure. As a matter of fact, it is good to understand the physical properties of loudspeakers so as to understand better of the overall power transduction efficiency. This paper describes a method of measuring a low-cost loudspeaker’s Thiele/Small parameter (T/S) for the thermoacoustic engine electrical generation application based on the method proposed by A.N.Thiele and Richard H. Small.
